摘要:
Disclosed herein are various systems and methods relating to communication devices that include modular transceivers, such as small form pluggable transceivers. According to one embodiment, a communication device may include a chassis defining an interior and an exterior of the communication device. The chassis includes a top, a bottom, and a plurality of sides that together with the top and the bottom form an enclosure. One of the sides may include a first segment disposed in a first plane and a second segment disposed in a second plane. The second segment includes an outwardly extending communication transceiver housing configured to receive a communication transceiver. The communication transceiver may extend through an aperture in the second segment and into interior of the communication device to contact an electrical connector, while a second portion of the communication transceiver in the communication transceiver housing remains on the exterior of the communication device.

An improved telephone line terminal block cover is disclosed. The particular block to which the invention has application is a horizontally mounted terminal block having upper and lower matched arrays of terminal clips projecting upwardly and downwardly from the upper and lower horizontal surfaces of the terminal block, respectively. The disclosure presents a flat, rigid, acid-solder resistant hinged terminal guard. The specific structure includes a hinged plexiglass or cellulose acetate door, overlying the upwardly extending terminal clips. The door is swingable upon the hinges upwardly away from the metal clips, to gain access thereto. The door shields the terminal ends from electrical shorting by accidentally dropped objects, and also guards against other terminal fouling debris, including wire clippings and/or solder drippings from soldering operations at higher level rows or banks of similar horizontally mounted terminal blocks; the guard also acts as a personnel protecting device, preventing accidental body contact with the terminals.

A flame suppression cabinet for printed circuit boards includes intumescent material that expands at an elevated temperature to block ventilation openings in a top panel. Fire suppression plates are positioned between adjacent ones of a plurality of printed circuit boards positioned vertically on a shelf rack in side-by-side spaced-apart parallel relationship to prevent fire from spreading between the circuit boards.

A device provided with fire protection includes a casing (102), electrical components (103) inside the casing, and a fan element (104). The casing includes a first wall having ventilation apertures and the fan element is configured to produce ventilation flow through the ventilation apertures so as to cool the electrical components. The device further includes a fire protection element (105) including thermally expanding material (109) configured to suppress the ventilation flow via the ventilation apertures in response to a situation in which the thermally expanding material is exposed to heat and gets expanded. The fire protection element is outside the casing, the fan element is mechanically supported to the casing, and the fire protection element is removable and re-installable without detaching the mechanical support between the casing and the fan element. Therefore, the fire protection element can be a post-installable element.
